ActiveRecord object.valid? triggers unexepected results

I'm editing an ActiveRecord object in a session through AJAX, updating
it with object.attributes = params[:object], and validating it with
object.valid?
Because it's associated with other objects in a form, I want to save
them all together.

The surprise was that object.valid? triggers after_validation_on_update.
I'm having an audit log and I was getting bogus entries.

http://api.rubyonrails.org/classes/ActiveRecord/Validations.html#M001316
valid?()
Runs validate and validate_on_create or validate_on_update and returns
true if no errors were added otherwise false.

valid?() should run all validations, but not trigger after_validation
callbacks.
This is not just a rant... I'm looking for solutions? How can I have an
audit log on updates and running valid()? without polluting my audit
log?

Well.. I gave my own answer. Replace after_validation_on_update with
before_update. I think the misunderstanding came from the fact that I
interpreted "after_validation on_update" when it actually was "after
validation_on_update".
